A Secure and Efficient Access Control Scheme Based on PUF for Health Information Systems

Abstract

Lightweight computing technology is the trend of future information technology. Related research technologies are applied to electronic health records and electronic medical records, and only consider the mutual authentication of users and the confidentiality of data transmission. In addition, most researches still rely on time-consuming modular exponential calculations, elliptic-curve based signatures and encryption algorithms. However, few studies can fully consider the development of lightweight access control mechanisms for health care information database systems. Physically Unclonable Functions (PUF) devices are based on unique physical changes that occur naturally in the semiconductor manufacturing process, resulting in unique identification and unpredictability. They are used in authentication and encryption mechanisms and have significant improvements in performance. This investigation discusses and analyses on the privacy protection, authorization and access control characteristics of the health care information database, and develops a secure and efficient access control scheme by using PUF technology for health information systems. The proposed access control scheme not only improves the privacy and security of patient medical records, but also makes the entire medical process more efficient.
